Jody,

Your problem is that first you have to visualize the task at hand and then
you visualize how the loop solves the problem.
Here is the loop I was mentioning:

{*******************************************************************
Description: Close of Day
Provided By: Omega Research, Inc. (c) Copyright 1999
********************************************************************}

Inputs: DaysAgo(Numeric);
Array: CloseArray[50](-1);

If DataCompression < 2 Then Begin
 If Date > Date[1] Then Begin
  For Value1 = 50 DownTo 1 Begin
   CloseArray[Value1] = CloseArray[Value1-1];
  End;
  CloseArray[0] = Close[1];
 End;
 If DaysAgo <= 50 AND DaysAgo > 0 Then
  CloseD = CloseArray[DaysAgo - 1];
 If DaysAgo = 0 Then
  CloseD = Close;
End;

{Forcing the function to series}
Value1 = CloseD[1];



The CloseD function keeps a value in an array for the Close of the last 50
days for the current symbol. As the chart progresses from day to day the
array needs to have the values slid back one each day. A loop is used for
that purpose.

Hope this makes it clearer than mud.
